iPhone Playing Music Through Bluetooth Speakers On Its Own

My phone is an iPhone XS Max and it keeps playing music on my bluetooth speakers with random music from My phones Music library. Some times it is doing it at night when I'm sleeping. I get around it by turning off the Phones Bluetooth but the following day the phone will find a way to "Turn ON" the Bluetooth and start playing at random again. My Bluetooth speaker is shared by my iMac, iPad and other devices who do not play at random, only the iPhone is doing it. Thing is even if I turn off the bluetooth in quick settings the bluetooth will turn on again the following day on its own and then start playing music if it feels like it. Im suspecting that someone at apple is turning it on and I think it is a privacy concern because I did not give any one remote access to my phone's controls.

My question is: How do you stop the phone from activating and playing on my bluetooth speakers at random times with random music even if the music app is closed?

I certainly hope that this problem is not in anyway paranormal in nature?

And I'm starting to believe that apple is accessing the phone as no one else has the ability to remotely control this phone except Apple.

I hope Apple can give customers some respect, because this product is too overpriced to be problematic and frustrating on a daily basis.

There is a section below that asks "What device is this about" all my devices are listed except this problematic iPhone XS Max so I chose a different device instead just to select the phone.

Really frustrated with Apple.

Too much Technology made them difficult on simple matters.
